- 1. It was indicated that a visual foreign object search and retrieval was performed at various locations on the secondary side of the steam generators (SGs). Please discuss the scope and results of any other secondary side inspections performed.
- 2. In prior SG reports it was indicated that the sludge height could have exceeded 3 inches.
It was indicated that for outer diameter stress corrosion cracking in the sludge pile, an examination for 3 inches above and below the top of the tubesheet was performed.
Please discuss why the entire sludge pile height was not inspected with a rotating probe.
Please discuss whether the chemical cleaning reduced the sludge pile height.
- 3. It was indicated that 34 indications of wear were identified in 27 tubes near the top of the tubesheet in SG A. Please discuss why table 3 does not list all 34 indications. If the indications were not sized, please discuss the basis for keeping these tubes in service.
